Math models can be useful tools for study of cancer progression

Using mathematical models, researchers in the Integrated Mathematical Oncology (IMO) program at Moffitt Cancer Center are focusing their research on the interaction between the tumor and its microenvironment and the "selective forces" in that microenvironment that play a role in the growth and evolution of cancer.

A melanoma cloaking protein

Johns Hopkins and Yale scientists have found that melanoma cells use a cloaking protein to hide from immune cells poised to attack the cancer. Nearly 40 percent of their sampling of melanoma tissues contained the B7-H1 protein, also called PD-L1, and scientists say it could be used as a target for new therapies.

Combination treatment effective against melanoma

Research from The Cancer Institute of New Jersey (CINJ) shows that a coordinated effort to block signaling pathways that promote cancer cell growth and survival enhances programmed cell death in melanoma.

Combination of Avastin and Metformin may effectively reduce melanoma growth

COMBINING the experimental drug Avastin (bevacizumab) with the diabetes drug Metformin almost doubles its ability to reduce skin cancer growth, according to a study in Cancer Discovery.

MEK1 mutation does not necessarily make BRAF mutant melanomas resistant to inhibitors

A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true.

Mayo Clinic researchers train mouse immune systems to eradicate skin cancer from within

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors.

XL888 inhibitor can prevent vemurafenib resistance in melanoma patients

Researchers at Moffitt Cancer Center in Tampa, Fla., and colleagues in California have found that the XL888 inhibitor can prevent resistance to the chemotherapy drug vemurafenib, commonly used for treating patients with melanoma.

New transfection method changes genetic material of cancer cells

Researchers at Polytechnique Montr-al have succeeded in changing the genetic material of cancer cells using a brand-new transfection method. This major breakthrough in nanosurgery opens the door to new medical applications, among others for the treatment of cancers.

Scientists identify molecular switch that controls ATF2's dual functions

The National Cancer Institute (NCI) estimates that as many as one in 51 men and women will be diagnosed with melanoma-the deadliest form of skin cancer-at some point during their lifetimes. A research team led by Ze'ev Ronai, Ph.D. at Sanford-Burnham Medical Research Institute (Sanford-Burnham) is working to unravel the molecular mechanisms underlying the development and progression of this disease in hopes of improving prevention and treatment strategies

Melanoma drug makes pre-existing cells with RAS mutation grow into skin squamous cell cancers

Patients with metastatic melanoma taking the recently approved drug vemurafenib (Zelboraf) responded well to the twice daily pill, but some of them developed a different, secondary skin cancer.

Fibroblasts play an apparent role in melanoma tumor growth

Fibroblasts, cells that play a role in the structural framework of tissues, play an apparent role in melanoma tumor growth. Fibroblasts also contribute to melanoma drug resistance and may also facilitate the "flare" response when a tumor's metabolism is enhanced following a patient being removed from a targeted therapy, said researchers at Moffitt Cancer Center in Tampa, Fla.

SU2C, MRA announce new Dream Team dedicated to melanoma research

Stand Up To Cancer (SU2C), the Melanoma Research Alliance (MRA) and SU2C's scientific partner, the American Association for Cancer Research (AACR), today announced a new Dream Team dedicated to melanoma research. Jeffrey M. Trent, Ph.D., and Patricia M. LoRusso, D.O., will lead the Dream Team project entitled "Personalized Medicine for Patients with BRAF Wild-Type (BRAFwt) Cancer."
